Answer:
y = -3x-4
Step-by-step explanation:
First we find the slope
m = (y2-y1)/(x2-x1)
= (-16 - -7)/(4-1)
= (-16+7) /3
= -9/3
= -3
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = -3x+b
Using a point
-10 = -3(2)+b
-10 = -6+b
-10+6 = b
-4 = b
y = -3x-4
The problem is saying that 17/20 times the number of dollars equals the number of euros converted. Which in this case to solve your problem, 17/20 times one equals 17/20.
point 1 = ( -1 , 5 ) point 2 = ( 5 , -5 )
equation of a line: y = mx + b
Find Slope (m):
( 5 - (-5)) / (-1 - 5))
= 10 / -6
= -3 / 2
slope = -3/2
Find y-intercept (b):
y = mx + b
y = -3/2 * x + b
5 = -3/2 * -1 + b <-------------- use the x and y coordinate of one of the . points. I used point 1 ( -1 , 5 )
b = 7/2 or 3.5
Assemble:
y = -3/2 * x + 3.5
Answer:
Adding and Subtracting Polynomials. When adding and subtracting polynomials , you can use the distributive property to add or subtract the coefficients of like terms. Use the commutative property to group like terms. (Recall that "like terms" are monomials with the same variables, such as 3 x 2 y and 82 x 2 y .)
